If in the conception of the gods in the Veda we find besides sensuous views important ethical elements, and traits transcending sense, we also find in the worship of the Aryas, in the relation of man to the gods, a certain simplicity coexisting with sharply defined ethical perception. Men pray to the gods for protection against the evil spirits, for the preservation and increase of the herd, for help in sickness, and long life, for victory in battle. It is allowed that sacrifices are offered in order to obtain treasures and wealth. Indra is to "give gift for gift;" he is to send wealth "so that one may wade therein to the knee." From this the god will obtain his advantage in turn; if Indra gives horses, chariots and bulls, sacrifices will be offered without ceasing.[103] Like flies round a jar of honey, we are told in another place, do the suppliants sit round the bowl of the offering; as a man sets his foot in the chariot, so does the host of minstrels longing for treasure place their confidence in Indra.[104] In a hymn, the minstrel says to Indra: "If I were the lord of cattle, master of such wealth as thou art, Indra, then would I assist the minstrel; I would not leave him in need."[105] But, on the other hand, it is emphatically stated that Indra rejects the wicked, as a man spurns a toadstool with his foot;[106] that no evil is concealed from Mitra and Varuna. It is left to Indra to give to the sacrificer whatever he considers best and most valuable; he is entreated to instruct the sacrificer, to give him wisdom, as a father to his child.[107] Stress is laid on the fact that sacrifice can remove a multitude of sins, and purify him who offers it, and we saw how earnestly Varuna was invoked to forgive the guilt that had been incurred.
